FILE - In this Oct. 14, 2011, file photo Eric Robert appears during a hearing in Sioux Falls, S.D. Robert pleaded guilty to killing Ron Johnson during a botched prison escape at the South Dakota State Penitentiary and asked to be put to death. A judge determined in October that the crime merited the death sentence, and Robert was scheduled for execution the week of May 13 but the state Supreme Court postponed the date in February to allow more time for a mandatory review to make sure the death penalty was proper, even though Robert hadn't appealed the conviction or sentence. The review could take up to two years. (AP Photo/Argus Leader, Emily Spartz, File)
